Sample .def file
; myfile.def : Declares the module parameters for the DLL.
LIBRARY "mylib" BASE=0x10000000 ; change the base to something better
; to avoid collisions with other modules
DESCRIPTION 'does a lot of useful stuff'
EXPORTS
myFunction ; no parameters or anything else, just name of function
myOtherFunction
This will turn off mangling as well as setting some useful parameters, like the default base address. Set this to something other than 0x1000000 as this is the default base for C++ modules (speed up loading time that way).

Hello moliate,
Thanks alooooooooooooooooooooot for your help.
IT WORKS
I can't believe it !
Now it works fine ...
Now i think, i can go and sleep in rest !
Really thanks and thank you for simple .DEF ...
I just have other question ...
If i define a enum like this:
enum Days
{
sunday = 0;
saturday = 1;
};
or classes and strctures ...
How about them ?
How could i define them in .DEF file ?
I must write only their names in .DEF ?

Those go in the header file.
However: using structs and classes as function parameters should generally be avoided, as it severly cripples the ability to use the module with other languages. Besides the fact that different languages have different memorylayout for classes, many languages can't handle pointers. Try keeping the module as neutral as possible.
BTW, I noticed that you were calling CoInitialize before loading the module. As you are using an ordinary dll (non-COM) that is not neccissary..
Cheers

Because it dont like these signature I also stick to the good old def-file and get my undecorated names.

Hi All,
Any idea why this wouldn't work?
BOOL bRes = m_cAnimCtrl.Open("PROGRESS.AVI");
if (bRes)
{ m_cAnimCtrl.Play(0, -1, -1);
}
Progress.avi exists in the same folder as the project and opens fine in Media Player.
Cheers,
Clodagh.

Maybe it's too complex for CAnimateCtrl to handle. Docs say something like it has to be uncompressed or RLE8, whitout palette changes ad a couple more restrictions. Try replacing with a simpler AVI to determine if this could be the cause.

The video is uncompressed. It's just a standard clock on a progress dialog - nothing fancy  )

Maybe its a path problem. Your app runs in another directory. Try the complete path. What ist with GetLastError() ???;)

Sub : Out of Memmory when loading the Project into the workspace
we are developing a small appl for storing images into a database using VC++ 6.0. Entr Edition. The database used is SQL Server 7.0. The problem facing is the image is not storing in the database. When trying to save the image an error is poping up saying "Invalid Locator de-referenced". When the same program is connected with Access 2000, it working fine.
Another problem facing is, sometimes, when we open the Project, it will not load. System saying that "Out of Memmory", mainly when loading resource file.
The machine config is i think quite okay, 128 mb, 500 Mhz Processor Speed (Pentium 3) with 1GB free space in the primary drive.
Thanks in advance

Hi
I have a problem and hope you can help. I have a software that creates a registry key unter HKEY_LOCAL_MACHINE/Software. Because of some Problems with that I had to change the access rights on the key SOFTWARE and add an user there and said in the regedt32 program that it shall exchange the access rights also for the sub keys too.
When I run my software and it creates the new key then this key géts automatical the same access rights from the SOFTWARE-key.
To make it easier for my customers I wanted to write a small tool that adds this special user and the access right to the SOFTWARE-key automatical and changes the access rights for the subkeys too (people are scared to work with regedt32 and change something).
Everything works fine ... I read the current users and add the new user to that key and then I go through the subkeys and make the same changes. The only problem is that when my original software is running and creates its own key that new key doesn't get the access rights from the SOFTWARE-key. My guess is that the tickmark in the regedt32 dialog is doing something else than just going through the tree and exchanging the access rights but also tells the main key that it shall monitor if new subkeys are created and give it its own new access rights too or something like that. Now the problem is that I don't know how to make my tool doing the same. Is there some kind of flag or function that I have to call so that every new created subkey has to get the same access rights like the SOFTWARE-key?
Thank you for your help

YOu can do this, but it's a little ugly. How I managed to do this was:
Get security settings of the key I'd like to emulate (e.g., HKLM\Software)
Set security settings on my new key to the settings I just got.
Check out RegGetKeySecurity and RegSetKeySecurity and that should put you in the right direction.
No generalization is 100% true.
Not even this one.
|
|
|
|
|
The Problem is that I'm NOT allowed to change the software who is creating that new
subkey so it would set the security settings by it's own like that.

Hi! Could somebody tell me how can i access the properties of standard C++ and additional AciveX controls?
I used VB before C and i was used to get/set a property using a simple command like (TextBox1.Text="Anything or else"'. But in C++ i cannot do this so simple. I tried to add a member variable (using the class wizard) for a CString type value(m_Text1) and for the control(Text1) either but they just don't work. The CString shows no connection between it and the value (it's always empty), and when i try to use the var. for the control (Text1.GetWindowText and Text1.GetLine) it says: unhandled error at 0x0000005?).
Please somebodi tell me the solution! Thanks!

OK, I will have a stab at this. Even though I have been drinking beer and haven't written any code in close to 6 months due to no job and to much reading and looking after kids.
Let's say you have a control called Ctrl1, you set the text using Ctrl1.SetWindowText("NewTitle") and retrieve the current value using Ctrl1.GetWindowText(StrToStore).
I hope that is what you were asking.

take a look at "UpdateData()"
it tranfers the text from the controls to the CString or from the CString to the controls
if very easy to use when you have many control in one dialog
you can also use the "SetWindowText" and the "GetWindowText" but you will have to write more code to get the same thing done

the problem is that;
you tried to access a CString type EditBox variable as if u are using a CEdit (control type) variable. GetWindowText and GetLine is available for control type variables. You can use the value whatever u write in EditBox inside your code easily getting the value (be it character or number) by UpdateData(TRUE); or display the new value (if u changed it inside ur code) by UpdateDate(FALSE)...
Visual C++ is not a toy..you will understand me in the future...

I've got a modeless dialog box which can be resized and I would like to set a minumum size for it, as it looks stupid if it is too small. Any ideas?
I tried editing the OnSize function like this (thinking that if it worked I could check for 'cx < MINIMUM_X' and change cx if required):-
void CDlg::OnSize(UINT nType, int cx, int cy)
{
cx = 200;
cy = 300;
CDialog::OnSize(nType, cx, cy);
// TODO: Add your message handler code here
}
It didn't work, the dialog stayed the same size. And when I looked at cx and cy in the debugger their values did not change (they were 605 & 573 when it entered the function and the same when CDialog::OnSize was called). I am very confused about why they did not change . Can anyone help?
Any comments welcome  .

Check out WM_GETMINMAXINFO. This will let you set min and max sizes for your dialog.
|
|
|
|

Thanks you for your reply.
I added a message handler for WM_GETMINMAXINFO to CMainFrame and that worked fine .
BUT i wanted to set the minimum size for a Dialog box and when I go to add a 'New Windows Mesage Event' for for the dialog box, WM_GETMINMAXINFO is not on the list  . Any ideas?

Yeah, that's a design flaw in VC++. You have to go to the last page of the class wizard - can't remember what it's called, alas, I've moved to VC7 and ClassWizard is gone - and then there's a silly little combo box labeled "class type" or something like that. Change it from "dialog" to "window" and all of the messages will be availale.

Ya, I looked for ever to find where to enter in OnPaint() handler for My dialog class. I would have added a menu for a Message handler dialog box when you right click the Class in the solution explorer like VC++6.0 had like the Project(I can't rememeber what the tab name is) window.

Hi All,
I have a resource bitmap and I could show it.
By the following line I could get a handle to it.
/*----------------------------------------------------------*/
hBit = LoadBitmap( hInst, "LASER");
/*----------------------------------------------------------*/
I also attach the hBit handle to a CBitmap object then use GetBitmap funtion to have a BITMAP variable.
now I wan to show this bitmap by only it is Red pixel values.
for exmaple:
if the RGB value of an pixel is 0x4f1254
I only what to get a new bitmap with the 0x4f0000 value of the same pixel.
How could I do it.

You may be able to do something fancy with raster operations, but I think it's more likely you'll need to grab a DIBSection wrapper and do something like the colour filter in my first image filtering article. The code is in C#, but it's easily ported.
